Specification of Letters Patent.

Patented July 30, 1907.

Application filed August 9,1905- Serial No. 273,466.

To all whom it may concern:

Beit known that I, EDWARD G. THOMAS, of New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improve- -ments in Carriers for Pneumatic-Despatch Tubes, of

which the following is a specification.

My invention relates to improvements in carriers adapted for use in pneumatic despatch tube apparatus and its principal object is to provide a simple and ellicient means for constructing the carrier shell, and for attaching to it the felt head or buffer, and a yielding ring at the opposite end of said carrier shell.

In the accompanying drawings which illustrate a construction embodying my inventionz-Figure 1 is an exterior view of the carrier showing the open end of same in section. Fig. 2 is a sectional view on line xx, Fig. 1 looking in direction indicated by arrow. Fig. 3 is'a sectional view of a portion of Fig. 1 showing method of fastening buffer to shell or cylinder. Fig. 4 is a section on line yy Fig. 3.

Like letters of reference refer to like parts throughout the several views.

The shell consists of'a' tube of cylindrical or other form, which carries an internal flange at one end. A plate H is located inside the shell, and may be centered by inwardly projecting ribs L formed in the car- I rier shell.

ing the felt by the washer I, and a piece of felt K may be inserted in the hole of the head B to cover the heads of the screws J.

The rear or open end of the carrier A is provided with an external flange E against which rests the felt ring F, which, when placed in the position shown in Fig. 1 is held against displacement by the split metal ring D sprung into the circumferential recess C and pressing against the said felt ring F. When the ring F becomes worn from use, the felt ring is removed, and another one substituted, after which the split ring D is sprung back into place.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a carrier for pneumatic despatch tube apparatus, a shell carrying an external flange at one end, a yielding ring adapted to fit over said shell and against said flange, a circumferential recess 01' groove in said shell, and means cooperating with said recess or groove for engaging and holding said yielding ring in position.

2. In a carrier for pneumatic despatch tube apparatus, a shell carrying an external flange at one end, a yielding ring adapted to lit over said shell and against said flange, a circumferential recess or groove in said shell, and a split ring adapted to be sprung into said recess or groove and to engage said yielding ring and hold the same in position. Y

3. In a carrier for pneumatic despatch tube apparatus, a shell carrying an external flange at one end, a yielding ring adapted to fit over said shell and against said flange, and a removable ring for retaining said yielding ring in position thereon.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this thirty first day of July A. D. 1905.

EDWARD G. THOMAS.
